One thing is to try and shoot your pictures to 'have something in the foreground'. I think this picture of trilliums with the two flowers up front fairly close works better than any number of photos I've taken of patches of trilliums
Stand far enough back from your subject to 'capture the context'. Here, I wanted a picture of the old mill and dam at Walter's Falls. But I think it was a lot more effective to shoot from further back and show the millrace, the water flume and some old machinery, than closer.
'Try a different viewpoint'. I've shot hundreds of pictures of big old trees, but a few years ago I tried this viewpoint. I found it very effective, and often shoot pictures like this now.
Tomorrow, breaking the rules about light.
